A carp is swimming approximately 8 1/4 beneath the water surface and a sunfish is swimming approximately 3 1/2 feet beneath the water surface. Which fish is swimming farther beneath the water surface?

The carp

Step-by-step explanation:

In this question, we are simply asked to find which depth is greater.

For the carp, it is swimming at a distance of 8 1/4 ft beneath the water. Now since 1/4 is same as 0.25, this means she is swimming at a depth of 8.25 below the water.

For the sunfish, it is swimming at a depth of 3 1/2 ft. 1/2 is same is 0.5. This means she is swimming at a depth of 3.5 ft

Obviously we can see that 8.25 is greater than 3.5 so we say that the carp is swimming at a farther distance beneath the water surface

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
